Core Tip Cell free DNA (cfDNA) carries information about colorectal cancer-specific genetic and epigenetic alterations which can aid in screening, detection and prognostication. Detection of genetic alterations is made difficult by low signal-to-noise ratio owing to an abundance of background non-tumorigenic mutations. Low amounts of cfDNA in healthy individuals negatively affects the sequencing performance and limit of detection of assays making screening non-feasible. One solution is to harvest cfDNA from peritoneal fluid or stool as this is more representative of the primary tumour compared to plasma-derived cfDNA. Alternatively, increasing the sensitivity of sequencing technologies would allow for the detection of low frequency mutations.
